Abstract

La présente invention se rapporte à un système de commande d'ouverture/de fermeture (1) destiné à commander le fonctionnement d'un orifice d'entrée de telle sorte qu'un environnement externe puisse être détecté de manière plus précise et que l'orifice d'entrée puisse être mieux ouvert et fermé. Un capteur d'environnement interne (22) dans un système de commande de ventilation (1) détecte l'environnement interne à l'intérieur d'un boîtier (10) et un capteur d'environnement externe (21), qui est disposé loin du boîtier (10) et n'est pas en contact avec le boîtier (10), détecte l'environnement externe à l'extérieur d'un boîtier (10) qui correspond à l'environnement interne. Une unité de calcul (31) acquiert les environnements interne et externe détectés par le capteur d'environnement interne (22) et le capteur d'environnement externe (21) et commande l'ouverture/la fermeture d'un orifice de ventilation (40) selon la différence entre les environnements interne et externe. Un tel système de commande de ventilation (21) permet que la détection de l'environnement externe par le capteur d'environnement externe (21) soit rendue moins sensible à l'effet de la présence du boîtier (10) et détecte de manière plus précise l'environnement externe. Par conséquent, l'ouverture/la fermeture de l'orifice de ventilation (40) peut être commandée de manière plus appropriée.
